Featuring all-new game tests, this benchmark is for use with Vista based systems. "There are two all-new CPU tests that have been designed around a new 'Physics and Artificial Intelligence-related computation.' CPU test two offers support for physics related hardware." There are four preset levels that correspond to specific resolutions. 'Entry' is 1024x768 progressing to 'Extreme' at 1920x1200. Of course, each preset can be modified to arrange any number of user designed testing. For our testing, I will use the four presets at all default settings.
- All default settings in each preset level
- Entry 1024x768
- Performance 1280x1024
- High 1680x1050
- Extreme 1920x1200
At the base clock frequency, the 655 has its hands full with the AMD lineup and the situation isn't much better when overclocked. The AMD PII quads just outperform it, while the Athlon lineup delivers slightly less grunt. The 875 at stock and overclocked speeds is still a powerhouse delivering performance that the AMD group does not come close to.
